In the Old Hillsbrad Foothills it is possible to get 1199 reputation by clearing all of the "Durnholde..." and "Tarren Mill..." before activating the events. This is an important note due to the fact that there are a few enemies that will despawn after you have completed the events and killed Epoch Hunter.

Revered reputation is required to teleport to Caverns of Time from Zephyr in World's End Tavern in Shattrath.

There is no reputation requirement to have Zidormi in the Violet Citadel in Dalaran teleport you to Caverns of Time.
